Evening primrose

Oenothera biennis is a biennial wildflower with large lemon-yellow flowers that open in the evening and release a pleasant fragrance. Flowering from summer into early autumn, it provides an important nectar source for moths and bees. Its upright growth makes it ideal for wildlife gardens, wildflower meadows, and sunny borders. This hardy species readily self-seeds under favourable conditions.

Care/Water

Oenothera biennis prefers consistently moist soil, especially during spring and summer growth periods. Water regularly to promote strong growth and long flower spikes. Avoid waterlogging to prevent root rot, as soggy soil can harm the plant. Consistent moisture ensures healthy leaves and encourages abundant flowering.

Maintenance

Remove faded flowers to maintain vitality and extend blooming. Regularly trim weak or damaged shoots to keep the plant compact. Apply organic fertilizer in spring to support healthy growth. Ensure good air circulation to prevent fungal diseases and maintain plant health.

Location

Oenothera biennis thrives in sunny to lightly shaded locations. Full sun encourages intense flowering, while light shade protects the foliage. Soil should be nutrient-rich and well-drained to ensure healthy roots. This plant is suitable for garden beds and larger containers alike.
